I do appreciate the response, and understand your point. I'm just a user, not a coder - and as a user I just wanted to make a point about the way Mame is used - at least in my world.
The thing is, I saw a new UI was coming, I guessed it wouldn't have autofire and enhancements, and knew right away that all the work going into the UI is of little use for me. It won't do what I want it to do.
Just saying.
Derivative builds are all well and good, but they do disappear too. By adding such things to the core UI would help raise the bar on what derivatives offer.
I know I'm stuck at .160 now, because that is the latest version of a derivative I can find that have the options I'm used to, and want.
